Answer:
ending balance: 8,750
Step-by-step explanation:
AR 78,000
uncollectible amounts 1% of sales
expected uncollectible amounts 875,000 x 1% = 8,750 --> ending balance
allowance for uncollectible beginning balance (4,000)
Adjustment 3,750 credit
We need to adjust for 3,750 to get expected uncollectibles.
